Another favourite and full of brilliant re-mixes is Saint Etiennes Casino Classics, particularly Underworlds re-working of Cool Kids of Death and the Chems, or Dust Brothers as they were then mix of Like a Motorway.

...is probibly the most brilliant one I've heard. Its a remix/mix of Dusk & Blackdown's album Margins Music, which is damn good as it is. He takes all the parts and makes a massive DJ mix out of it all and remixes stuff.
